Rules
Go Up to Supported Objects
Rules promote data integrity by allowing you to validate the values supplied to a table column. They are reusable objects that you can bind to table columns or user datatypes. For example, you can create a rule, bind it to a column in a table and have it specify acceptable values that can be inserted into that column.
